Through drawing the inlet channel 119 that heating element 113 and casing 110 formed, can make the in-process that the outside air got into heating tube 113b from inlet channel 119 earlier gradually preheated by heating tube 113b, thereby make the air that gets into heating tube 113b be the hot-air, be favorable to improving the aerosol release amount of atomizing medium carrier 100, take away the heat of casing 110's inner wall simultaneously, reduce the heat and to the outer transmission of casing 110, make the thermal-insulated effect of heating mechanism better, also make the heating mechanism be difficult to send out the boiling hot when having improved thermal utilization ratio. Optionally, the first extraction portion 113e is provided with an air inlet 116 for allowing the external air to enter the heating mechanism, and the air inlet 116 is communicated with the air inlet channel 119.

Of course, in other embodiments, the external air is not limited to enter from the air inlet channel 119 formed by the above-mentioned extraction heat generating assembly 113 and the housing 110, but may enter from a side close to the bottom 113d of the heat generating pipe 113b, for example, from the mounting seat 115a, and at this time, the preheated external air is less.

In some embodiments, the central heating assembly 115 further comprises a protective member 111. The protection member 111 is positioned in the housing 110 and detachably connected with the housing 110, the extraction member 113a and the heating tube 113b are positioned in the protection member 111, and the extraction member 113a and the mounting seat 115a are detachably connected with the protection member 111.

In one embodiment, the mounting seat 115a is magnetically coupled to the bottom of the receiving cavity, and the magnetic coupling force between the mounting seat 115a and the receiving cavity is smaller than the assembling force between the mounting seat 115a and the protection pipe, so that when the protection member 111 is removed from the housing 110, the mounting seat 115a can be removed from the receiving cavity together with the protection member 111. In another embodiment, the second extraction portion is detachably connected to the housing 110 by snap-fit or magnetic attraction, and the protection tube and the mounting seat 115a are not locked to the housing 110.

In one specific example, the first seal 117 is a silicone ring. Of course, in other embodiments, the first sealing element 117 is not limited to a silicone ring, and may be a sealing element made of other materials.

In some embodiments, the center heat generating assembly 115 further includes a second sealing member 115f, and the second sealing member 115f is positioned between the center heat generating body 115b and the support member 115c to seal a gap between the support member 115c and the center heat generating body 115 b. The second seal member is arranged to prevent the flowable dirt generated by the heating of the atomizing medium carrier 100 from easily entering the mounting seat 115a along the outer surface of the center heat-generating body 115 b.

In one particular example, the second seal 115f is a silicone sleeve. Of course, in other embodiments, the second sealing element 115f is not limited to a silicone sleeve, and may be a sealing element made of other materials.
